Crystal Palace defenders Damien Delaney and Joel Ward have yet to agree new deals at the club.
Blackpool are considering offering terms to Jonathan Legear, with it up to the Belgian midfielder to prove his fitness.
Harry Redknapp is looking to bring another striker into Queens Park Rangers, but doubts that he will secure the services of Carlton Cole.
Cole is currently available as a free agent after reaching the end of a previous deal at West Ham United.
Various clubs were linked with an approach over the summer, but the England international is still without a club.
He has returned to training with West Ham as a result, in an effort to earn fresh terms, and Sam Allardyce has admitted to being keen on getting the powerful frontman back on board.
With it expected that he will re-sign for the Hammers, Redknapp concedes that he will have to look elsewhere for support to Charlie Austin - his only fit forward.
He said after a 1-0 victory over Yeovil Town on Saturday: "We want a striker, but clubs won't let them out on loan.
"We need help up front, that's for sure.
"Charlie's doing a good job but he needs some help. He can't keep doing it in every game, we need to take the pressure off him.
"Carlton's a great player, but I think he's going to sign for West Ham."
